Start every day coding, end every day thinking.

1. Warmup exercise (30 mins)

Make sure to have these ready the night before, pick stuff
that you can work on right away without having to study 
in advance. 

They can either be book exercises or stuff
from other sources, but they should be self-verifiable

Whether you're trying to give back to the open source community or collaborating on your own projects, knowing how to properly fork and generate pull requests is essential. Unfortunately, it's quite easy to make mistakes or not know what you should do when you're initially learning the process. I know that I certainly had considerable initial trouble with it, and I found a lot of the information on GitHub and around the internet to be rather piecemeal and incomplete - part of the process described here, another there, common hangups in a different place, and so on.

In an attempt to coallate this information for myself and others, this short tutorial is what I've found to be fairly standard procedure for creating a fork, doing your work, issuing a pull request, and merging that pull request back into the original project.

Creating a Fork

Just head over to the GitHub page and click the "Fork" button. It's just that simple. Once you've done that, you can use your favorite git client to clone your repo or j

This guide assumes that you recently run brew upgrade postgresql and discovered to your dismay that you accidentally bumped from one major version to another: say 9.3.x to 9.4.x. Yes, that is a major version bump in PG land.

First let's check something.

brew info postgresql

The top of what gets printed as a result is the most important:

const isWalkable = value => value !== null && typeof value !== 'undefined';
const getChild = (parent, child) => (isWalkable(parent) ? parent[child] : undefined);
const getIn = (descendants, origin) => descendants.split('.').reduce(getChild, origin);
